About this plugin
Fake accounts come with fake addresses: mailboxes that do not exist, domains without a mail server, throwaway inboxes. CAPTCHAs stop some robots, not the addresses. MailProbe checks the address itself, in real time, without sending any email to it.
At registration (the WordPress registration form and the WooCommerce “My account” form), the address is checked before the account is created. The visitor is refused, with a clear message, when the address:
- cannot receive emails: no mail server for the domain, mailbox that does not exist, bad format;
- is disposable (a throwaway inbox);
- is a shared address such as info@ or contact@, if you choose to refuse those (off by default).
”.
Your real customers get through. Some addresses cannot be confirmed by anyone: domains that accept every address, and providers that do not allow checks, such as Outlook and Hotmail. They are never refused, because most of them belong to real people.
The visitor waits three seconds at most, and if MailProbe cannot answer in time or cannot be reached, the registration goes through. No code is sent to the visitor’s inbox, so nobody is lost to a code that lands in spam.
WooCommerce orders are never blocked. After each order, the billing email is checked in the background. The customer does not wait.
When the address cannot receive emails or is disposable, the order gets a private note (with the corrected address when it looks like a typo) and a red mark in the orders list, so you can check before you ship or before your follow-up emails bounce.
Works with the classic checkout and the block checkout, and with the WooCommerce orders tables (HPOS) as well as the older storage. WooCommerce is optional: without it, the plugin protects the WordPress registration form.
Pricing
The plugin is free. Each check uses one MailProbe credit. A MailProbe account comes with 100 free checks; after that, credits are prepaid, with no subscription, from $5 for 1,000 checks.

Privacy
MailProbe is run by Iris Digital and hosted in the EU (France). Addresses sent for a check are processed in real time and not stored once the check is done. The plugin adds a suggested paragraph to your site’s privacy policy page (Settings > Privacy).
External services
dev), an email verification service run by Iris Digital, France. It is what decides whether an address can receive emails.
What is sent, and when:
- When someone submits the WordPress registration form or the WooCommerce “My account” registration form, and the form has no other error: the email address entered.
- After each WooCommerce order, if “Check orders” is on: the billing email of the order.
- When you open the settings page or save a new API key: nothing but the key, to read the credit balance.
Each call carries your MailProbe API key and identifies the plugin and the versions of WordPress and WooCommerce. It does not carry your site’s address or any other customer data. Nothing is sent until you add an API key.
